From 0d8382ae70e7559eba873b4d8b2cf9a15aeccf20 Mon Sep 17 00:00:00 2001 From: Jelle van der Waa Date: Tue, 23 Feb 2016 18:47:19 +0100 Subject: sunxi: power: add support for sy8106a driver SY8106A is a PMIC which is used on the Allwinner H3 Orange Pi Pc and Plus board. The VOUT1_SEL register is implemented to set the default V-CPU voltage to 1200 mV. This driver is required to ensure the SY8106A V-CPU voltage is set to 1200 mV after a software reset. On cold boot the default SY8106A output voltage is selected to be 1200 mV by a pair of resistors on the Orange Pi PC and Plus.
